Admin Only Labels for Product Options

I have a clothing store that has different sizing available for different manufacturers. For the customer they just need to see “Select a Size” for me I need to be able to create 10 different option fields all named “Select a Size” but need to have a way to differentiate between different manufacturers. Adding an extra field for an admin only label would be great!

I’m sure there are other areas in the system that could use Admin Only labels as well, I just have not dug that far into it yet.
